Hi,
I found a bug in my application, there was no commit at all in all the
indexing chain.
I noticed thanks to this bug that lucene keeps a file system reference
to deleted index files. So after many files indexed I hit a Too many
open files.
I use a 32 bits 1.6.16 JVM on a linux 64bits system.
Directory is opened using factory : FSDirectory.open(dir)
So I guess NIOFSDirectory is returned.
We use a merge factor of 4.
NOTE: that we use lucene for a long time and never had this problem.
clues are : - it's the first time we use 3.0.1
- it's the first we forgot to commit on a large
collection (10k docs).
Here is a chunk of lsof linux utility (which output open files)
(There is a total of 16225 files in this case)
